, 'BefitlfknmvnfthatiIfEanLiJnonNEnG, a ,citizenof'the' German Empire,=anda resiident ofDuss'eldorf, Germany,- have invented Machines 'f 'for Securing Covering-Strips to Cans,joffwhibh ltheffollowing is a specifica# tion.. n 4 n i ThisV invention vr'elates to a vmachine for taining?"paintsorA` others substances and to which thel coverhas been- -already applied. `Thefconstruction1is such that the'strip is applied tightly and without wrinkles tothe fthe i-'oi'setv"formed between said parts., In j'V this Waythe cover is vprevented `from coming o'fsfaridv 'at "thesame 4time -a ldust and air is a. side'elevation of a machine embodying my invention,A with :some of the' parts omitfted 2.a vert-ical section of fthehold'er; Fi 3 :rsimilarsectiontaken at right angles to; ig.f 2 Fig;L 4f a plan of the'tlap folding strip:y in consecutive positions. n .i The-textile of otherlsse'aling blanks or ,strips 1 are'stacked up in-a m'a'g'azine'2,over" tently rotated drum 3. During its rotation .'the drum is 'engaged by a roller 4:' adapted to cover the sanielwithan adhesive; When .a coatedA face ofthe drum arrives'above against thedrumgl so thatt "the uppermost' strip will adhere thereto and will be taken "galongthereby. From drum 3, the strip is removed by 'the horizontally reciprocative tongs 5 which place'it upon a can 6. The cans are fed forward by an endless conveyer i 7, whichI places 'them singly upon a verti- -cally' movable table or plunger 8. The latter receives its motion from shaft 9 carrying 4.5 cam 10, which is' engaged by lever 11, connected by' an adjustable rod 12, with arm n A 15 of talle 8. As soon as strip l has been superposed upon the can, a springso that'A a pad 16 carried'by the' lever is pressed against the striprso as to paste the same to the can cover. As soon asthe tongs are retracted Fig. 1) lever .13 is swung out ofthe patlrrof table 8, .and the latter is.

raised to lift the can into a holder or fold- -means?Figs.'.15,f6;-l{and Sshow the 'can and/ l l Specicaton of Letters latent. Patented Uct, 31, 1911, l "Abpncation' mea-october 5.1910. seriain. 585,347.

I ing devicevv 1.7El adapted to receive the same.-

Th'is holder is provided on two opposed sides with brushesV 17, Vwhile the two other sides are provided Withresilient tongues Y18,-the4 Width of which corresponds 'to the width of lthe can. Thus as the can is pushed -into the holder, the projectingends ofthe strip are turned down 'over the ends of the can, so as to form creased flaps extending beyond the. can ends.

'(Fig. 6). The sides ofthe strip are` bythe brushes t forced tightlyn against the sides of the cover and the can body, nothwithstanding'the oti'set formed between cover and can.' Table 8 which had meanwhile been retracted, willnow ascend to project "a new can into the holder, which second ,can will push thetirst can out of the 4 holder and into the path of a laterally mov able :slide 19.. This slide is actuated from. .,5

shaft 9 by cam 20,V and connections 21. 'The displaced can will with its upper end arrive' within the path-of :1U-shaped folder 22,

having pins 22b that are guided intubulararms 23. This folder is by slide 19 normally lheld in the position indicated 'in Fig. 2

against the action of springs 24.` 1f the slide.. `is moved tothe left, folder 2 2 is-librated `so that springs..24-willfadvance 1they same,

and vproject its fingers 22 over two of the flaps of strip .1, so that such flaps are folded against the can'ends (Fig. 7). lThe movement of the folder is limited by stops 25 carried by pins 22h and which are adapted' o engage arms 23, while the slide is at liberty to continue its movement. During' suoli further movement, .he slide will engage the can, and push ,the samebetween two yieldingly journaled rollers 2G, These rollers are carried by slides-27 having longitudinal slits which are engaged by guide pins 28 of the machine frame.v Slides'27 are' influenced by springs 29,. that tend to I push the slides together with their rollers inwardly. .Rollers 26 will thus fold the two remaining flaps of strip 1 over the previously folded flaps, at the two can ends (F ig. 8). Slide 19 being now -retracted will take along folder 22 against action of springs 24, so as to return the same to its original position. At the next advance of slide 19, the can carried thereby, will push theprior can "into a passage 30, having'.

brushes 31 along its top. These brushes -press thefolded liaps against the sides of the cover and the can body, so-that the cover is securely tightened up 0n all of its fourl sides. The subsequently fed into 'pas` sage 30, willpush the' prior cans along said passage, sothat they are eventually carried by'a ,conveye'r or slidewayto a suitable acicunlulating receptacle. n
